IIVIPROVEMEN'I IN WASH-BOILERS.

Specification forming part of Letters Patent No. 121,370, dated November28, 1871.

To all lwhom it may concern:

Be it known that I, MARIA C. HUBEAED, of Troy, in the county ofRensselaer and State of New York, have invented certain new and usefulImprovements in Clothes Steaming Apparatus 5 and I do hereby declarethat the following is a full, clear, and exact description thereof,which will enable others skilled in the art to make and use the same,reference being had to the accompanying' drawing forming part of thisspecijcation.

This invention relates to the operation oi cleansing clothes 5 andconsists in a supportingframe and in rods in combination with theordinary washboiler, arranged as hereinafter described.

In the accompanying drawing, Figure l is a top view of a boiler providedwith my steaming apparatus. Fig. 2 is avertical longitudinal section ofFig. l taken on the line x x.

Similar letters ofreference in dicate correspon ding parts.

A is the boiler, of the common oval or other form and of any size. B isaframe or hoop, which may be made adjustable so as to iit boilers otdifferent sizes, which is suspended in the boiler by means ot' hooks Oor supported in the boiler near the top in any otherinanner. It may besupported on a bead or projections in the boiler but, to adapt it toboilers already made or in use, I prefer to support it by hooks, asrepresented. On the top of this frame, or near the top of the boiler,supported in any manner and kept in position in any manner, I place oneor more longitudinal rods, D, and one or more transverse rods, E, as maybe found necessary.

F is the cover of the boiler, Which is made to iit as nearly steam-tightas convenient.

A small quantit,- of water is placed in the boiler and the clothes to bewashed are soaped, hung upon the rods, and not allowed to touch thewater.n The cover F is placed on the boiler and the water is made toboil. be exposed to the steam only. There will be a slight pressure ofsteam within the boiler owing to weight and friction, and thetemperature of the steam will be, coiilsequently, somewhat higher thanthat of the water. The water, which condenses on the clothes, will dripdown by its own gravity. The action of the steam upon the clothes veryspeedily removes the dirt and thoroughly clcanses the clothes, norubbing being necessary. The time required for cleansing the clothes ismuch less than when the clothes are immersed and boiled in the usual Wayand after boiling the clothes must be rubbed, while the steaming'thoroughly cleanses them. This result is mainly owing to the fact thatthe clothes are not packed tightly together as in boiling, but hangloosely in the boiler in a temperature somewhat higher than 2I2O.

Having thus described my invention, l claim as new and desire to secureby Letters Patent The frame B and rods D E, combined as described, withboiler A F, as and for the purpose set forth.

. The above specification of my invention signed by me this 10th day ofOctober, 1871.
